Description

Interface Summary

DataBuffer	DataBuffer defines an interface for data sources that can provide full random access to the elements they contain.
DataSource	DataSource defines an interface for classes that can express their content as data streams.
DataStream	DataStream represents a stream of data elements of some specific type.
XMLDataStream	Marker interface for streams of XML type

Class Summary

CollectionDataSource	CollectionDataSource represents a data source that uses a standard Java collection to implement a source of DataValue elements.
DataBuffers	DataBuffers provides tools for DataBuffer manipulation.
EnumDataBufferType	EnumIndexType defines a data type that provides mapping from integer indexes to DataBuffer values.
EnumeratorDataStream	EnumeratorDataStream represents a data stream that uses a standard Java enumerator to implement a stream of elements.
EnumeratorTypeStream	EnumeratorTypeStream represents an enumerator data stream that enforces the common stream type over all stream elements.
IndirectDataBuffer	IndirectDataBuffer is an abstract base class for DataBuffers which are implemented on top of other DataBuffers.
IteratorDataStream	IteratorDataStream represents a data stream that uses a standard Java iterator to implement stream elements.
IteratorTypeStream	IteratorTypeStream represents an iterator data stream that enforces the common stream type over all the stream elements.
JoinedDataBuffer	A JoinedDataBuffer makes a data buffer out of several parallel buffers.
JoinedDataStream	A JoinedDataStream makes a data stream out of several parallel streams.
LazyListDataBuffer	LazyListDataBuffer implements a delayed initialization list data buffer.
ListDataBuffer	ListDataBuffer represents a data buffer that uses a standard Java list to implement a buffer of DataValue elements.
ListIteratorDataStream	ListIteratorDataStream represents a data stream that uses a standard Java list iterator to implement stream elements.
PivotDataStream	PivotDataStream represents a data stream that has the processed results of PivotDataSource.
ProxyDataBuffer	ProxyDataBuffer provides a single column view to a multi column buffer.
ResultSetDataStream	A ResultSetDataStream makes a data stream out of a SQL result set.
ReversedDataBuffer	ReversedDataBuffer implements a reversed view to the underlying data buffer.
SimpleDataBuffer	SimpleDataBuffer is a DataBuffer implementation for single DataValues.
SortDataStream	SortDataStream represents a data stream that has the processed results of SortDataSource.
StreamDataSource	A StreamDataSource makes a reuseable data source out of a data stream that can be read only once.
TupleDataStream	A TupleDataStream allows tuple elements in a tuple data stream to be rearranged at will, or to make ordinary data streams tuple streams.

Package com.davisor.data.stream Description

This package extends the data framework package with tools for working with data streams and buffers containing data framework data objects and arbitrary data objects. The classes in this package implement, in particular, stream tools for convenient data delivery and sharing accross Java collections and SQL databases. The package also implements some generic data stream encoders.

This package is used by many other packages in this source tree, in particular the graphics chart generation package. The tools in this package must not refer to any other package than the core and data packages.

Since:

JDK1.2
